As shown in said patent, the nozzle is mounted on an arm which is pivoted to the form member of the press, and as the press is operated. the nozzle is moved in over the pile of stock to be printed to pick up the top sheet, which is thereafter conveyed to and placed onto the platen.

it is the object of this invention to provide an improved nozzle of the character shown in the patent aforesaid, to which also reference is made for a complete di closure of the op eration of the nozzle. The invention is illustrated in the accompanying drawings in which Fig. l is a diagrammatic view of a portion of a Chandler 85 Price job press showing the nozzle in position.
